In the third step of performing a first cutting process 2 on the aluminum alloy structure 50, the first color layer 60 is partially cut to form the first working groove 61, and the first working groove 61 is passed through the first color layer 60 and extended into the surface 52 of the aluminum alloy structure 50 so that the color of the surface 52 of the aluminum alloy structure 50 is exposed outwardly from the first working groove 61. Preferably, the first working groove 61 has an annular shape. In the third step of performing a first cutting process 2 on the aluminum alloy structure 50, the first cutting process 2 is performed by turning, milling, planning and the like.

In the fifth step of performing a second cutting process 4 on the aluminum alloy structure 50, the first color layer 60 is partially cut to form the second working groove 62, and the second working groove 62 is passed through the first color layer 60 and extended into the surface 52 of the aluminum alloy structure 50 so that the color of the surface 52 of the aluminum alloy structure 50 is exposed outwardly from the second working groove 62. Preferably, the second working groove 62 has an annular shape. In the fifth step of performing a second cutting process 4 on the aluminum alloy structure 50, the second cutting process 4 is performed by turning, milling, planning and the like.
